BISCUIT-CONTAINER.

Specification of Letters Patent.

Patented July 29, 1919.

Application filed June 26, 1918. Ser1a1No.24l,932.

To all whom it may concern:

Be it known that we, ROY E. TOMLINSON and HENRY H. Huxonnroun, citizens of the United States, the former residing at Montclair, in the county of Essex and State of New Jersey, and the latter residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in! Biscuit-Containers, of which the following is a specification.

Our invention relates to the formation of metal containers for holding biscuits or the like food products, and the object of our invention is to provide containers which may readily and economically be manufactured and filled, which shall be effectively sealed against air, gas and moisture and which may readily and easily be opened without the use of any instrument. One of the particular points which we have in contemplation 1s the provision of such containers which may be used for military service overseas, and which will be entirely proof against poison gas and at the same time be readily opened byla simple manipulation. We provide such a container by slitting the metal blank for a sufficient distance and then soldering a metal strip, known as a taggers tin, over the slit. The blank is formed into an elongated container, in which the crackers or other goods are inclosed, the ends of the package being suitably closed and the slit referred to covered over by the metal strip, extending partway around the container, midway between its ends. It is desirable to have the slit extend across what may be termed the top of the container (in the case of a rectangular container), and partway down the two sides, the metal being scored from the ends of the slit to the bottoms of the sides. The metal strip or taggers tin is soldered at' its edges so as to make the slit airand gas-tight, the strip being, however,

not soldered to t e container.

forming part of this application and illustrating one embodiment thereof. In the drawings, Figure 1 represents a perspective view of a closed container embodying our invention, Fig. 2 is a view partly in elevation and partly in longitudinal section'of the closed container, Fig. 3 is a side elevation of the container in partly open position, and Fig. 4 is a cross section taken on line H of Fig. 2.

Referring to the drawings, the container represented generally at 1 is formed of tin or other suitable metal, the body portion of the container being suitably closed as by soldering the same along a longitudinal seam 2, shown at the bottom of the container. The ends are closed by suitable closures 3, 3. which may be secured to the body portion in any suitable manner to make an airand gas-tight closure. For example, flanged end pieces may be set in the ends of the body portion of the container and the double wall thus formed rolled outwardly in well-known manner, to form the beads 4, 4.

The slit 5 extends entirely across the side 6 of the container, which may be termed the top side, and partway down the adjacent vertical sides 7, 7. This slit is cut through the metal before the blank is shaped into the form of the container, and at the same time the metal is preferably scored along the lines 8, 8 in alinement with and continuation of the ends of the slit 5, these scorings preferably extending to the bottom edges of the vertical sides 7, 7 of the container.

The metal strip or taggers tin 9 is secured to the blank to entirely cover the slit 5 by soldering the same along its edges to the blank. One end of the taggers tin is pro vided with a 100 or bent-up fla 10 which is he workman runs his soldering iron lightly along one edge of the taggers tin 9, as shown at 11, then along theop osite end of the taggers tin, which is pre erably beveled, as shown at 12, and returns along the other side edge of the taggers tin, the soldering iron being passed across the taggers tin below the end of slot 5 and adjacent to the flap 10, to sweat the soldenacross strip 9 at this point. The end 12 of the strip is preferably beveled, as stated, to facilitate the soldering iron passing around the taggers tin at its end withwhich would make the opening of the package more diflicult.

The container being filled with biscuits 13, for example, the opening of the same is readily efl'ected by outward pull on flap 10, whereupon the gers tin is entirely removed. The contamer then being held on opposite sides of the slit 5, downward pressure on the two end portions results in the metal easily opening along the scored lines 8, 8, the two halves of the container swin ing 0 about the line 14 as a bin e, t e line esignated 14 extending across t e bottom side of the container between the lower ends of the scored lines 8, 8. Preferably, there is no scoring along the geometrical line 14, so that the two halves of the container swing open about this line as a hinge without separating entirely, as shown.

While the container has been described as of rectangular section, it will, of course, be obvious that it may be of circular, triangular, or other desired section, in which cases the slit 5 (and scored lines 8 if used) will extend for suitable distances, so that an unbroken line or portion of the metal will remain, about which the two end portions of the container may swing open, as described.

What we claim is 1. A container for food products, comprising an elongated continuous casing, en-

tirely closed and tight when filled, having a slit extending partway around the same, intermediate its end portions, and a thin strip secured along its edges to the casing to cover said slit, said strip having an unattached end by which' the strip may be pulled OE, and said casing being adapted to swing open about a line in alinement with said slit, when pressure is applied on opposite sides of said slit. A

2. A container for food products, comprising a casing, entirely closed and tight when filed, havlng a slit extending partway around the same, between its end portions, and havin lines scored thereon in continuation of said slit, for rt of the remainder of the periphery of t e casing, and a thin strip secured to said casing to cover said slit, said strip having an unattached end by which the strip may be pulled 011', and said casing being adapted to swing open along a line in alinement with said sllt and scoring, when ressure is applied on opposite sides of sai slit.
